Better vision while you sleep

If you're mildly to moderately nearsighted, you may be interested in corneal refractive therapy. It's a new kind of contact lens that reshapes your cornea and corrects your vision while you sleep. You have to wear them every night, which could be a hassle for many people. But they're no riskier than extended-wear contacts and they're approved by the U.S. Food and Drug Administration.
